のエネルギーを節約するような水の循環法に関する。[Detailed Description of the Invention] (Purpose of the Invention) U Industrial Field of Application The present invention is used to melt snow on the roofs of buildings, roofs built on sidewalks, roads, parking lots, etc. in snowy areas. The present invention relates to a water circulation method that saves source water, such as groundwater, that serves as a heat source for non-sprinkling snow melting, and the energy required to pump this source water.
［従来の技術］

あるいは地下に洒養している。[Conventional technology] Snow melting methods that use groundwater as a heat source are widely used because they are cheaper than other snow melting methods that require an energy source. There is a non-sprinkling snow melting method that allows water to flow through the pipes. In non-sprinkling snow melting, usually a single pump is used to pump up groundwater and pass water through the snow melting pipes, and the water from the snow melting pipes is either discarded as is or stored underground.
［発明が解決しようとする問題点］
ところで、近年、地下水の汲み上げによる地盤沈下など
の問題が生じて地下水の使用が制限される傾向にあり、
水を多く使用する散水融雪は、放出した水の水質上直接
地下へ洒養することはできない。[Problems to be Solved by the Invention] In recent years, problems such as ground subsidence due to pumping of groundwater have arisen, and the use of groundwater has tended to be restricted.
Sprinkling snow melting uses a lot of water, and due to the quality of the released water, it is not possible to directly recharge it underground.
一方、無散水融雪においてはこのような問題はないが、
債雪時には常時高揚程の揚水ポンプを運転して地下水を
汲み上げて融雪管内に通水するので、地下水の使用量が
多いとともに動力の消費量も多いといった欠点があり、
水源水の使用量が少なくて済み、しかも運転エネルギー
ガ節約でき、低温水により効率的に融雪できる融雪法が
望まれている。On the other hand, snow melting without watering does not have this problem, but
During snowfall, high-lift pumps are constantly operated to pump up groundwater and pass it through the snow melting pipes, which has the disadvantage of using a large amount of groundwater and consuming a lot of power.
There is a need for a snow melting method that requires less water source water, saves operating energy, and can efficiently melt snow using low-temperature water.

A circulation pump passes the water through the snow melting pipe, and the water tank is divided into a high temperature tank into which source water flows, a low temperature tank into which return water from the snow melting pipe flows, and the water in the high temperature tank and the low temperature tank are mixed to form the snow melting pipe. It detects the temperature of the water in the medium temperature tank and controls the operation of the water pump based on the detected value, detects the temperature of the snow melting management membrane, and controls the circulation based on the detected value. The operation of the pump is controlled to maintain the temperature of the water supplied to the snow melting pipe at a predetermined value.

The water is returned to the medium-temperature tank through the tank, where it is mixed with water from the high-temperature tank, raised in temperature, and reused. If the water temperature in the medium-temperature tank is above a predetermined value, the water pump continues to stop, and when the water temperature falls below a predetermined value, the water pump is operated for a certain period of time.
High-temperature water from a water source is supplied to the high-temperature tank to raise the water temperature in the medium-temperature tank, and the water temperature in the medium-temperature tank, that is, the temperature of the water supplied to the snow melting pipe, is maintained at a constant value.

'The water pump 4 is operated only when the water temperature in the intermediate temperature tank 11 is below a predetermined value. Medium temperature tank! The predetermined value of the water temperature of I is set to a value that has a snow melting effect and is lower than the water temperature of the high temperature tank IO to some extent.

用途に供される。The operation of the circulation pump 5 is performed when the ground temperature of the snow melting management facility 2 falls below a predetermined value. This is because it can be estimated that it is snowing or snowing. This predetermined value varies depending on the location and season in which the snow melting device is used, so it is appropriately set to a value that matches the conditions. When the circulation pump 5 is activated, the water sucked by the circulation pump 5 from the intermediate temperature tank 11 is sent to the snow melting pipe 3 via the circulation pipe 17, radiates heat in the snow melting management facility 2, and is transferred to the snow melting management facility 2. After melting the snow on the surface and lowering the temperature, the snow passes through the return pipe 18 and is discharged to the upper part of the cryostat 12. When the circulation pump 5 is not operating, the liquid levels in the medium-temperature tank 11 and the low-temperature tank 12 are at the same level, and when the circulation pump 5 is activated, the water in the medium-temperature tank 11 is pumped up, the liquid level is lowered, and the return pipe 18 As the circulating water flows into the cryostat 12 and its liquid level falls, the liquid level in the cryostat 12 relatively rises,
A water flow is generated from the low temperature tank I2 to the medium temperature tank 11 through the weir 14. When the water pump 4 is in operation, the liquid level further rises, and when it reaches a set level or higher, water is discharged from the bottom of the cryostat 12, which has the lowest temperature, via the outflow pipe I9. This wastewater can be drained underground or used for other purposes as needed.

By mixing the temperature-reduced water used for snow melting in the medium-temperature tank 11 with source water W at a constant temperature, which is intermittently supplied by controlling the operation time of the water pump 4, circulating water at the required temperature can be easily obtained.

It consists of a high temperature tank into which water flows, a low temperature tank into which water from the snow melting pipe flows, and a medium temperature tank which mixes the water from the high temperature tank and the low temperature tank and supplies it to the snow melting pipe. detecting the temperature of and controlling the operation of the water pump based on the detected value, and
This system detects the temperature of the snow melting management equipment and controls the operation of the circulation pump based on the detected value to maintain the temperature of the water supplied to the snow melting pipe at a predetermined value. When the temperature of the used water is below a predetermined value, the pump only needs to be operated for a certain period of time, and there is no need to operate it all the time. By circulating water to snow melting pipes, snow can be melted efficiently, enabling energy-saving operation, and in the case of groundwater pumping,
It also has the effect of restoring the well water level that dropped during pumping while pumping is stopped. Since the snow is melted without watering, the return water is not contaminated, and even if it is directly pumped underground, it is not subject to regulations regarding groundwater pumping.
